ATTACHMENT FOR LAVATORY-OUTLET VALVE DEVICES.

Applicationfiled October 24,1925, Serial No. 64,571.

The present invention relates to improvements in attachments forlavatory outlet valve devices of the type which is actuated byreciprocating a push rod that is in turn connected with. means foropening and closing a lavatory waste valve. v

It is customary topro'vide such valve, actuating push [rods withenlarged heads or handles and as commonly constructed, the base of suchheads or handles contacts-with the outer end of thecap or escutcheonwhich iscommonly provided about the push rod at the outer end of theguide or passage in the stationarymember of the fixture or wall tuatingmeans of various types but in the accompanying drawing isshown inconnection with a particular means which constitutes the subject of acompanion application.

In the drawings Figure 1. is a vertical sectional AV1W through alavatory waste valve actuating,

means embodying the invention.

Figure 2 is a detail. [The particular type of valve illustrated is thatcommonly known as a pop-up drain and includes atubular valve having anen- =larged head 1 which is adapted to be seated in a properly shapedvalve seat 2 provided in the bottom of the lavatory basin 8. The tubularvalve is provided with lateral openings or ports 4 through which thewaste water from the basin willtlow when the valve is lifted to raisethe head 1 from the seat 2 and when the valve head is seated on theseat'Q or in closed position, said ports it-cooperate with a channelformed in the body of the basin and communicating with an overflowopening 5 therein. Reciprocatmn of the valve is effected by a 7 which isfulcrumed within a suitable 1 progecting laterally irroitmtne.

valve fitting and has its inner end suitably .connectedwith the valve sothat as the lever is rocked about itsfulcrum, thevalve will bereciprocated to or ,from the seat.2. The lever 7 is connected w th apush rod shown ,as being of such form that the length thereof maybevaried to accommodateit to basins of vdifferent depths, although it willbe evident that a single or one-piece push rod may be, employed as thedetails of this do not constitute a novel feature ofrthe present.invention. i

The push rod 8 extends upward through a guide 9 which is adapted to besecured to aportion of. the basin-orto any other relativelystationarysupport. As shown, this guide, comprises a sleeve-likebody 9having an exterior thread formed. thereon and pr0- videdat its outerendwith an annular flange 10. The flange 10 is adapted to contactfandoverhang the outer face ofthe supportvll to whichthe guide issecured andpreferably a suitable washer ;12 is arranged between such surface andthe flange. I

'An' escutcheon 13, preferably made of vitreous material, ispositione'dabout the outer end of the guide and, as shown, isgheld inposition'by an annular flange on a sleeve 14 which is threaded into theguideand bears againstthe outer end of the escutcheon.

The lever actuating rod 8 extends through the guide andv on the'outerend thereof is secured a knob or handle 15.

ates with the inner endof the sleeve, 16 may be formed in any suitablemanner. As shown, the inner end of the guidehas an openingthrough whichthe push rod Sex-- tends. which is of slightly less diameter that theinterior bore of the body of the guide so thatan annular shoulder isprovided about .the push rod and with this shoulder the;,in- .ner end ofthe sleeve '16 contacts; to limit inward or downward movement of;thepush ro'd.

From, the drawing 'it will be seen that when the push red has beendepressed to the limit of its possible movement, the knob or handle, asrepresented in the dotted lines, will be some distance above the flangeof the escutcheon retaining member 14.

To cushion the force of the shock produced by contact of the lower endof the sleeve 16 with the interior shoulder on the guide 9, which forceis transmitted through said guide and escutcheon retaining member to thevitreous escutcheon, and effectually guard against fracturing theescutcheon we provide suitable pressure absorbing means above and belowthe escutcheon.

As illustrated a flexible, for example rubber, gasket 30 is interposedbetween the upper end of the escutcheon 13 and the flange on theretaining member 14. A similar gasket, 31, is interposed between thelower face of the escutcheon and. the metal washer 12; and as shown thisis supplemented by a smaller flexible washer, 32.

The yielding gasketsreferred to effectually protect the escutcheon fromdamage re sulting from violent depression of the knob or handle 15.

As a precaution against the possibility of clamping the escutcheon tootightly the periphery of the flange on the securin member 14L ispreferably smooth, having no corrugations or special means for beinggripped. In other words, the tightening of the member 14; is effectedonly by the plumbers fingers.

The guide 9 may be attached to the sup port 11 by any suitable means. Asshown, a washer 20 surrounds the threaded stem or body of the guide andthrough this washer extend a plurality of set screws 21, which areadapted to be turned into close engagement with the inner surface of thesupport. A nut 22 engaging the thread on the guide 9 bears against thewasher 20 and the guide is thus flrmly secured to the support 11.

It will be seen that when the parts are properly adjusted the ends ofthe washer 20, which as shown in Figure 2 is preferably of substantiallyelliptical form, are deflected downward from the points of contact withthe nut 22.

The washer 20 need not necessarily be of resilient metal, cast brasshaving been satisfaetorily employed. In assembling the parts the nut 22is to be screwed up until the washer begins to bend, and thereafter thescrews 21 are set up until the head of each is practically flush withthe outer edge of the washer.

From the foregoing description and the drawing, it will be seen that theinvention provides a very simple but effective means for preventing theescutcheon 13 from being injured by blows delivered by the knob 01'handle at the outer end of the valve operating rod.

There can, of .course, be considerable vainvention,

' flange about its outer end, an escutcheon surrounding the rod andextending over the flange at the outer end of the guide, means engagingthe guide and escutcheon for holding the latter in position, and meansfor limiting movement of the rod through the guide to prevent contact ofthe knob or handle thereon with the escutcheon.
